Anthophyllite and Halite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Anthophyllite and Halite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anthophyllite and Halite Optical Properties during the identification of gemstone. Specific gravity of Anthophyllite is 2.17 whereas that of Halite is 2.17.
